Summary Iron and McIlwraith Ranges IBA is one of the few known localities for the endangered Buff-breasted Button-quail. It supports an isolated population of the vulnerable Southern Cassowary, and populations of another three Cape York restricted-range species and four biome-restricted species.
Site description The Iron and McIlwraith Ranges are the most northerly extent of the Great Dividing Range, located in the north of the Cape York Peninsula, 750 km north of Cairns. The boundary of the IBA was drawn to encompass most of the area of closed forest in the region as well as significant areas of heathland vegetation suitable for White-streaked Honeyeater. This includes the Iron Range National Park, Iron Range Resources Reserve and the forested part of the Mungkan Kundju National Park. A range of other tenures is present within the area including aboriginal freehold and leasehold land. Much of the area has very poor sandy soils formed from eroded granite, which only support stunted heath which dominates this area. Richer soils produced by older, more easily eroded metamorphic rocks support lush rainforests, found to the east below the escarpment. The Iron and McIlwraith Ranges support the largest area of tropical rainforest on Cape York Peninsula which has close affinities with New Guinea. While many species found at Iron Range occur nowhere else in Australia, all these also occur in much larger numbers in New Guinea.

Other biodiversity Iron and McIlwraith Ranges is significant for a number of species that mainly occur in New Guinea. Some examples include the cuscus Phalanger intercastellanus and Spilocuscus maculatus, the rufous spiny bandicoot Echymipera rufescens. The area also encompasses the entire known Australian distribution of the snake Morelia viridus. Cape York endemic species that are entirely confined to this area include the marsupial Antechinus leo, the varanid Varanus keithhorni and the frogs Cophixalus crepitans, C. peninsularis and Litoria longirostris. The Iron Range area is also the site of a closed tussock grassland ecosystem that is currently considered endangered (Sattler and Williams, 1999).
Protection status The IBA overlaps with seven protected areas, two of which (Iron Range National Park and Iron Range Resources Reserve) are wholly contained within the IBA.
